16 claims. (C1. 15s-99) This invention relates in general to a burner as a marginal plate I having an offset inner rim for fluid or gaseous fuels and has more particu- I I which normally supports an open framework lar reference to a reversible burner for a gas 0r grillinot shown)` below which the gas burnstove. ers are placed. A burner of this kind Vmust be An important object of the invention is in the supported a short distance below the top of the provision of a burner of this kind consisting of plate I6 in order to obtain the most eicient rea single casting which may be used in either a sults inV heating, but if the burner is located too iight or a left position. low it will not allow sufficient space for a burner A further object of the invention is in the protray I2 below the burners.

of the casting so that a single burner casting In the inlet I4 is a passage 4I extending from may be utilized for both right and left burners. top to bottom and somewhat segmental in cross Referring now more particularly to the drawsection, the top and bottom being covered by A ing, a support for a gaslburner is represented segmental plates 42 and 43 each secured in place 55A near its axis by an adjustable fastening screw 44 so that either of these plates may be readily adjusted from the bottom of the casting when it is in position by simply loosening the screw 44 and adjusting the corresponding plate 42 or 43 to admit more or less air. The top plate is left ,closed to prevent dirt or other material from clogging the inlet.

I5 and of theV inlet portion I4 are inclined toward each other, and each face is parallel to the opposite face of the other portion; and the straight tubular portion I6 is located at one side of the burner portion I5 and connected theretoV by the inclined or angularly disposed portion II. This makes itfpossible to avoid the extreme depth of head which would be necessary to maintain the upper burner face atl the right distance below the stove top and also to connect the inlet with the burner valves 28.

With this burner the straight tubular portions I6 are located on a line with the stems 25, and the connecting neck portion VI'I is inclined upwardly to left or right position as shown by Figs. 7 and 8. This inclination requires that the opposite faces of the burner portion be inclined to each other so that they will be parallel with the stove top i0 in both positions; and the supporting faces of the projection I8 are similarly, but oppositely disposed to uphold the upper face of the burner in a level position parallel with the top.

At the inlet I4 end of the fitting the bottom face covered by plate 42 or 43 (depending upon its left or right position) is parallel to the opposite upper face of the burner portion I5, and is maintained in a horizontal position. Air adjustment is made by varying the position of the bottomplate 42 or 43, the top plate remaining closed,V and preventing dirt from clogging the air inlet opening at that side.

By this construction, the neck portion II is inclined upwardly, maintaining a proper flow condition for the fuel, with the upper burner face in level position, and the tapered passages in the ring-shaped burner portion I5 also help to equalize the pressure of the fuel mixture, as the portion I'I is connected to the side having the larger passage, resulting in a more uniform pressure from all of the burner ports.

Extending laterally fro-:fn each burner casting I3 is a projection 50 having a supporting ledge 5I with a projection 52 thereon at each side of the Vprojection 50. This ledge is for supporting a short burner 53 preferably resembling the burner portions on the castings I3 and having short projecting legs 54 for engaging the uppermost ledge 5I of its burner castings I3 at the opposite sides of the projection 52 and thereby holding this end of the burner 53 in place. The other end of the burner 53 is connected'by a hollow stem 55 with an inlet 56 which may be similar to the inlet I4 but preferably has only one air controlling plate 42 and adjusting screw 44 for controlling the air inlet to the burner 53. It will be understood that these burners 53 are not reversible and therefore they do not require a double face or the double inlet construction described in connection with the burner castings I3.

With this construction a single burner casting I3 is provided for both right and left burners and the corresponding face of the burner only is provided with the fuel discharge openings 38 and'39, depending upon whether the burner is turned for one face or the other; the connection of each burner casting is the same at the front and rear ends; and the supporting projections 50 being the same on both sides, will properly support the short burners 53 and hold them in proper position.

To mount the burner castings I3, the supporting bracket 20 may first be attached to` the slotted extension I3 by the screw 22, the opening 25 of the inlet I4 is applied tothe stem 26 and the projections 23 of the supporting bracket 20 willv then engage the openings 24 in the rim II of the plate i, holding the burner firmly in place so that it will also support the burner 53 when applied to its projection 50.
